Hello,

Alarms and Events generated after the Summer-Winter switch, notice the star before the time. As the time is changed 1 hour as per daylight saving, a star before the timestamp indicates that the alarm/event has occurred during the change period.

No, the same alarm comes before and after without that *. It's only in that time stamp, its coming with *.
